Question Description:

20.50

A rock stuck in the tread of a 52.0cm diameter bicycle wheel has a tangential speed of 3.20 m/s. When the brakes are applied, the rock’s tangential deceleration is 1.20 m/s^2. What is the magnitude of the rock’s angular velocity at t = 1.50 s? What is the magnitudes of the rock’s angular acceleration at t = 1.50 s? At what time is the magnitude of the rock’s acceleration equal to g? (Remember that you need to include both tangential and radial accelerations in computing the magnitude of the rock’s acceleration

Answer

20.50
